“…UWB systems present the greatest challenge of overcoming interference with narrowband systems such as WiMAX (3.3 to 3.7 GHz), WLAN (5 to 6 GHz), and X-band ITU (8.025 to 8.4 GHz). Therefore, it is crucial to minimize the interference at these frequency bands by involving band rejection techniques [15]. Notch antennas have been known for compact designs and have originally been used in missiles and aircraft flying surfaces.…”

This article presents the design and analysis of a V-shaped ultrawideband (UWB) antenna and dual-band UWB notch antenna. A rectangular slot is cut into a semicircular partial ground plane of the antenna to achieve ultrawide bandwidth. A U-shape slot is etched on a V-shaped patch that radiates, and an inverted U-shape parasitic resonator is placed beside the feedline to generate dual-band notch characteristics. The overall dimension of the proposed antenna is 28×23 mm2. The proposed UWB antenna has a gain of 9.8 dB, S11 < −10 dB, impedance bandwidth in the range of 3.4 to 12.3 GHz, response with a linear phase, group delay <1 ns, and stable radiation pattern. The UWB notch antenna shows strong rejection in the WLAN band from 5.15 to 5.8 GHz with a notch at 5.6 GHz and X band from 9.1 to 10.5 GHz with a sharp notch at 9.6 GHz, having a S11 < −10 dB impedance bandwidth ranging from 3.2 to 11.7 GHz. This antenna also exhibits a stable radiation pattern, group delay <1 ns, and linear phase response throughout the bandwidth except at the rejection frequencies.

“…The band-rejection can be achieved by implementing slots of certain lengths in the radiating patch or the feed line [6,[15][16][17][18][19][20]. In this design, a rotated C-shape slot is etched in the radiating patch as shown in Figure 4.…”

<p class="Default">In this paper, a new approach to the design of an UWB monopole antenna with dual band-notched characteristics is presented. The antenna has the form of an elliptical monopole over a ground plane having an elliptical slot to achieve the UWB. The dual-band notch function is created by inserting a U-shaped and a C-shaped slots on the radiating patch, thus no extra size is needed. The proposed antenna shows a good omnidirectional radiation pattern across the band from 3.2 to more than 14 GHz. The dual band-rejection is for 4.88-5.79GHz centered at 5.4GHz and 7.21-8.46 GHz centered at 7.8 GHz. The antenna prototype using the FR-4 substrate with ε<sub>r</sub>=4.3 has a compact size of 25mm×25 mm ×1.45mm. The fabricated prototype showed experimental results comparable to those obtained from the simulations.</p>

“…So, it is required to design UWB antennas that are able to notch the above bands to avoid electromagnetic interferences with the UWB systems [1]. Different techniques have been employed for the design of UWB antennas to obtain single, double, and triple band-notching functions [2][3][4][5][6][7][8][9][10][11][12][13]. The notching at a certain frequency was achieved by inserting a slot in the shape of the letter U [2][3][4][5].…”

“…A C-shaped narrow strip was connected at one of its ends to the elliptical radiating patch to achieve the band notch [11]. An open-ended λg/4 hook-shaped slot was used in [12] to obtain a single band-notched characteristic. Defected ground compact electromagnetic bandgap (DG-CEBG) designs were used to accomplish notches in WiMAX and WLAN bands [13].…”

An UWB semi-circular-shaped monopole antenna with double band-notching is presented. The suggested antenna is designed to have two notched-bands to avoid the undesirable interferences with the 3.5 GHz band for WiMAX system and the 5.5 GHz band for WLAN system with a simple structure. The first notch is realized by etching an arc slot in the arc patch. Whereas the other notch is achieved by adding a T-shaped stub on the feeding line. The suggested antenna has a small size of 30 × 25 mm2. The proposed antenna achieves UWB conditions. It operates within a wide band from 2.7 to above 18 GHz with two rejected bands at 3.5GHz and 5.5GHz. The performance of the suggested dual bandnotched UWB antenna has been investigated using the CST Software Package. An equivalent circuit of the proposed antenna was realized and investigated. The lumped elements employed in the equivalent circuit modeling of the suggested monopole antenna were determined using the Advanced Design System (ADS) software.
